RTCIceCandidate and RTCIceCandidateInit will be made spec-compliant. The RTCIceCandidate interface describes an ICE candidate in WebRTC. It is available in Chrome, but it is not spec compliant as it is missing some fields. There are also some deviations from the spec in terms of nullable and read-only attributes and errors thrown by the constructor.
